Color discrimination of deutan and protan observers through tinted soft contact lenses

Abstract

The effects of tinted soft contact lenses on the color discrimination of nine red-green color deficient subjects was assessed with two different clinical tests. Relative to the no-tint trials, individual differences on the Farnsworth-Munsell 100-HueTM test occurred; however, the results were inconsistent across subjects. These erratic differences were probably attributable to fatigue and motivation. The tinted lenses did not affect performance on the Ishihara Plate Test.TM
